Digital Communication

Abstract

Many educational training institutes are adopting information communication technologies (ICTs) as a part of their teaching and learning strategies. There are many reasons for this adoption, such as the implementation of eLearning, which is becoming a more prominent form of delivery in the education sector, also providing students with a global competitive edge. However, South African educational institutions still face many disparities in effectively implementing eLearning. The chapter impresses on the importance of the usage of ICTs for teaching and learning. It is vital to learn the challenges lecturers and teachers face using ICTs to enhance the teaching and learning environment; the effective usage of ICTs for eLearning implementation for teaching by lecturers and how students respond to these new digital formats. Technology Acceptance Model (TAM) in conjunction with the Constructivism Theory (CT) are also discussed while promoting digital compliance.

Randomly-based Stepwise Multi-Level Distributed Medical Image Steganography

“…Security and confidentiality of data transmissions are two of the most important factors for which image steganography is so important [2]. As new technologies emerge and people become increasingly reliant on data communications and the information they hold, the need for greater levels of security and privacy has never been greater [3]. Despite the claims of many protocols and applications, attackers are always one step ahead of the security measures.…”
